Corrected fuel flow is the fuel flow that is required by an engine if the freestream total head conditions are equivalent to ambient conditions at Sea Level on a Standard Day (i.e. 14.696 lb/in², 288.15K ).

Corrected Fuel Flow can be calculated as follows, assuming Imperial units:

So-called Non-Dimensional Fuel Flow ) is proportional to Corrected Fuel Flow:

Corrected Fuel Flow (or Non-Dimensional Fuel Flow) is one of several non-dimensional groups associated with gas turbine performance calculations.

The equivalent equations for Preferred SI Units are:


  • Stagnation (or Total) Pressure
  • Stagnation (or Total) Temperature
